    "abstract": "The present note establishes the self-averaging, radiative transfer limit for\nthe two-frequency Wigner distribution for classical waves in random media.\nDepending on the ratio of the wavelength to the correlation length the limiting\nequation is either a Boltzmann-like integral equation or a Fokker-Planck-like\ndifferential equation in the phase space. The limiting equation is used to\nestimate three physical parameters: the spatial spread, the coherence length\nand the coherence bandwidth. In the longitudinal case, the Fokker-Planck-like\nequation can be solved exactly.",
